Abstract

In communication system, a method of optimizing MPEG-7 transmissions between a server and an one or more clients, a first ADL (application descriptive language) which is a subset of MPEG-7 DDL (Description definition language) being translated into binary for communication to the first client, the method comprising: receiving, by the first client, the binary communication of the ADL; and translating, by the first client, the binary communication into the first ADL, the binary communication being translated using a frequency table, and an XSLT (XML style translation) document for translating MPEG-7 into the first ADL.

Claims

1. In communication system, a method of optimizing MPEG-7 transmissions between a server and an one or more clients, a first ADL (application descriptive language) which is a subset of MPEG-7 DDL (Description definition language) being translated into binary for communication to the first client, the method comprising:

receiving, by the first client, the binary communication of the ADL; and

translating, by the first client, the binary communication into the first ADL, the binary communication being translated using a frequency table, and an XSLT (XML style translation) document for translating MPEG-7 into the first ADL.

2. The method of claim 1 further comprising

generating the first ADL from the MPEG-7 DDL.

3. The method of claim 1 further comprising

generating, by the server, the XSLT document.

4. The method of claim 1 further comprising

generating, by the server, the frequency table for translating the first ADL into binary.

5. The method of claim 1 further comprising

downloading, by the first client, the frequency table and the XSLT, prior to receiving the binary communication.

6. The method of claim 1 wherein translating the binary document into the first ADL further comprises

generating, a decoding codebook for the binary communication using the frequency tables and the XSLT document.

7. The method of claim 1 further comprising

communicating information carried by the binary communication to a second client via the server.

8. The method of claim 7 further comprising

translating the first ADL into the binary communication;

forwarding the binary communication to the server;

translating, by the server, the binary communication into first ADL;

translating the first ADL into the MPEG-7 DDL; and

translating the MPEG-7 into a second ADL different from the first ADL.

9. The system of claim 8 further comprising

translating the second ADL into binary communication for forwarding to the second client.
